Infection of baboons ("Papio cynocephalus") with rotavirus (SA11)

Developments in Biological Standardization
S S KalterT L Lester


A recent survey of nonhuman primate sera indicated that antibody to a rotavirus (SA11) was prevalent among a wide spectrum of animals. Both New and Old World species were found with antibody, many with surprisingly high titers (1:320). Whether or not infection per se was due to SA11 or an antigenically closely related agent could not be determined by that study; however, it is apparent from this study as well as from a survey of the literature that natural as well as experimental infection of nonhuman primates occurs. Recognizing that there is a need for an animal model for the study of viruses associated with human diarrhea, a preliminary investigation attempting to ascertain the susceptibility of the baboon (Papio cynocephalus) to a rotavirus was undertaken. Inoculation of four newborn baboons with SA11 resulted in diarrhea within 24 to 48 hours in all animals. One animal died 10 days postinoculation following severe diarrhea and dehydration. Virus was isolated as well as seen by electron microscopy in the stools of all four animals.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
